Summary
The optic system of chick embryos was used to study axonal transport during early embryogenesis. Axonal transport of proteins from the retina to the contralateral tectum could be detected by radioautography following intraocular injection of3H-leucine in 7 day old embryos. The rate of transport was approximately 5mm/day, and no evidence was obtained for a more rapid axonal transport at this stage.
